AAA Quench Oil

Description

‍

AAA QUENCH OIL is a clear, gold colored product designed to provide maximum cooling rates for austenitized steels. Its formulation guarantees good stability due to its accelerator package which will not stratify out at any temperature nor can it be filtered out. AAA QUENCH OIL can be used as a quench from temperatures as high as 1750°F and is especially suitable for developing maximum oil quenched hardness in medium and low alloy steels. It is widely used as a quenching medium for carburized and carbonitrided work as well.

‍

AAA QUENCH OIL is known as a fast quench oil, achieving rapid cooling rates in the nucleate boiling stage immediately following a short vapor phase. It also provides a slower cooling rate through the martensitic transformation range (Ms-Mf) than competitor’s fast quench oils. This ensures higher and deeper hardness levels are created without accompanying distortion of parts. Testing demonstrates AAA QUENCH OIL's superior heat removal characteristics are the difference between partial and complete hardening in actual practice.

Overall, distortion in oil quenched parts is proven to be caused by sluggish, non-uniform cooling rates. This is due to the thermal variations and mixed microstructures in the initial stages of the quench which slower quench oils produce. A fast uniform quench is especially important in batchtype carbonitriding furnaces to provide all portions of the load becoming evenly hardened. The quenching rate provided by AAA QUENCH OIL was designed to satisfy this requirement. Additionally, this low viscosity quench oil drains off parts quickly resulting in less drag-out and is characteristically easier to wash off work after quenching. If left on, it provides a thin film of protection from rust.

You can use AAA QUENCH OIL with confidence. Your parts will achieve maximum oil quenched hardness with minimum distortion or cracking. Lastly, AAA QUENCH OIL will produce exceptionally clean, bright work when used within its recommended temperature range.

Key Properties

• Formulated to provide maximum cooling rates for austenitized steels, suitable for achieving maximum hardness in medium and low alloy steels. The oil is known for its fast quenching ability, particularly in the nucleate boiling stage, which ensures rapid cooling immediately following a short vapor phase. This characteristic helps in achieving deeper and higher hardness levels without causing distortion or cracking of the parts.
• A clear, gold-colored fluid with a viscosity ranging from 14.0 to 19.3 cSt at 100°F. It has a high flash point over 340°F, enhancing its safety by reducing the risk of fire during use. Its formulation includes an anti-oxidation agent which ensures that the oil maintains its properties and does not stratify or filter out at various temperatures.
• Effective across a broad range of operating conditions. It can be used in open tank operations at temperatures between 77°F and 180°F, in vacuum operations up to 130°F, and under a protective atmosphere up to 200°F. This versatility allows it to be used in different quenching environments, adjusting to the specific needs of various metallurgical processes.
• Maintain optimal performance, the oil may need periodic centrifuging or filtering to manage sediment levels. It's essential to prevent water contamination, as water can severely disrupt the quenching characteristics and pose fire hazards.
